M invention relates to the manufacture of slioes, especially McKay and cemented process shoes.

In the manufacture of McKay shoes, the

present practice is to assemble an insole and an upper over a wooden last that has a metal plate secured to its bottom, and then attach the upper to the insole by means of tacks or staples driven through the lasting allowance ofthe upper and insole and clinched against the metal plate on the last'. Theinsole and the tacks or staples remain in the shoe permanently and the tacks often cause much discomfort to the wearer, The principal object of this invention is to rovide a process of manufacturing Mc ay shoes without an insole orl tacks in the fore part thereof.

My invention consists principally in dis'- pensing with the usual insole in the part of the shoe between the ball and the toe. It also consists in using asock of'paper or the like overthe fore part of the last and cementing the shoe upper thereto, after which the last is removed and the outsole securedto said upper and the sock torn out. It also consists 1n the shoe and in the process of making same hereinafter described and claimed. In the accompanyin drawin which forms part of this specihgcation an wherein like symbols refer to like parts wherever they.

occur,

Fig. 7 is a partially the line 7 7 of Fig. 5,

Fig. 8 is a plan view with parts broken sectional view alongv Vball of the last and is provided with openings 3 near each end. A special sock 4 made of durable paper or the like is placed over the fore part of the last 1 and a shank piece 55 5 extending from heel to ball of last is secured to said last by means of tacks 6 driven through the openings 3 and into the wooden last. A shank stiifener 7 is then attached to said shank piece 5 by driving tacks 8 through 70 the shank piece 5.

Cementing material 9 is' then'applied to the sock and a shoe upper 10 while the former is stretched over the fore part of the last and the shoe v,upper 10 lasted over the sock,t'he 75 front latin 'allowance 11 of the up er 10 bein tacke to the last by means o tacks 12 t atae driven only part way into the last. The tacks 12a in` the `part of the shoe from the heel seat to the ball or".break line of the shoe are driven home and upon strik- ,l ing the metal plate 2 on the bottom of the last clinch the shank piece 5 to the upper, and remain as a permanent part of the shoe.

, After the cement that holds the upper to the sock sets, the tacks 12 in the fore part are pulled -out together with the tacks 6 which hold the shank piece to the last. The lasting allowance of the upper is then smoothed, an outsole 13 is laid,'and temporarily held by 90 any suitable means such as by cement 15; and then said last 1 is removed from the shoe. After the last is removed the outsole 13 is secured to the shoe by stitching 14, which .holds together the upper, shank piece and outsole in the usual manner, and the sock 4 is then preferably removed from the inside of said shoe by tearing the same therefrom;

but where the outsole is to be secured by stitching 14, such stitching is done after the last is removed from the shoe. Obviously, if desired, the sock 4: may be left in the shoe as a permanent part thereof and the finished shoe will have practically all of the advantages of a shoe Without an insole in the fore part.

Preferably fibrous material 16, such as cotton or the like is placed in the bottom of the fore part of the shoe in order to obtain an even base for the foot. It is noted that a cushion piece 17 may be seWed or cemented on the inside of the shoe in order to cover the fibrous material, provide a neat appearance for the inside of the shoe, and obtain a cushioning effect for the foot. It is also obvious that the outsole 13 may be rabbete'd around the edge so that the rabbeted portion 18 will receive the lasting allowance and provide an even surface on the inside bottom of the shoe.

What I claim is:

1. The process of making shoes, which comprises cementing a shoe upper to paper stretched over the fore part of a last for holding said upper in shape, tacking a shank piece that extends from heel seat to ball of last to said last, laying on an outsole, removing said last, and permanently securing said outsole to said shoe upper and said shank piece.

2. The process of making shoes, which comprises placin a paper sock on the fore part of a last, tacing a shank piece that extends from heel seat to ball of last to said last, temporarily cementing a shoe upper to said sock for holding said upper in shape, tacking said upper to said shank piece, laying on an outsole, removing the last, securing said outsole to said upper and shank piece and removing the paper sock.

3. rlhe process of making shoes, which comprises cementing. a shoe upper to paper stretched over the fore part of a last for holding said upper in shape, tacking a shank iece that extends from heel seat to ball of ast to said last, laying on an outsole and securing the same to said upper and said shank piece, and removing said last.
